SET-UP AND SECURED COLLAPSIBLE OR KNOCKDOWN BOX.

SPECIFICATION forming part of Letters Patent No. 681 ,472, dated August 27, 1901.

Application filed May 14, 1900.

T aZZ whom it nuty concern.-

Be it known that we, WILLIAM P. BIRNI E, a resident of Springfield, and CHAUNOEY W. GAY, a resident of West Springfield, in the county of Hampden and State of Massachusetts, citizens of the United States of America, have invented certain new and useful Improvements in Set-Up and Secured Collapsible or Knockdown Boxes, of which the fol- IO lowing is a full, clear, and exact description.

This invention relates to an improved setup and stuck paper or pasteboard box which has creases or folds therein, whereby the same may be knocked down and rendered into flat form to occupy but little space for packing and transportation, the .box being, however, readily available to be distended into its rectangular form in readiness for the reception of its contents.

The present improvements are especially available and valuable for comparatively deep and entirely-closed boxes, such as necessary for use for containing granulated and powdered substances, such as cereals, coffee, and the like.

The invention consists in the single pieceor blank of cardboard or similar stock peculiarly shaped and formed with creasing 0r folding lines, whereby the especial one-piece 0 box may,be completed and set up and thereafter collapsed or knocked down.

The improved box is fully illustrated in the accompanying drawings, in which- Figure 1 is a perspective View of the im- 3 5 proved box shown as set up. Fig. 2 is a perspective view of the same shown as partially collapsed or knocked down and making apparent in what manner the same may be rendered further contracted. Fig. 3 is a plan view of the blank of whicli'thenimproved box Serial No. 16,657. (No model.)

resent the sections which constitute the ends or edges of the box, b 1) indicating the staysections. d (:1 represent staysections or tongues at the ends of the bottom section 0 and adapted to make a close joint when the box is set up and stuck where the side walls or edges of the boxjoin the bottom. y represent the creases or folding-lines on which the blank is bent for the purposes of making the rectangular box of ordinary form, it being understood that the opposite sides are set up at right angles to the bottom and the per tions 12 b bent at right angles to the sections a as also are the stay-sections 12 b which are stuck to the sections 12 and the bottom stay-sections d are also stuck to the parts constituting the ends or edges 1) of the box.

to to represent the folding or creasing lines which render the box capable of being collapsed after the same has been completed. These folding-lines are arranged as follows: The end or edge walls I) b have the foldinglines 00 midway between the corners of the box, said folding-lines extending longitudinally and being continued in the creasingline a from end to end of the bottom a of the box. 00 1: represent creases or folding-lines extending from the corners of the box inwardly on the bottom at angles of forty-five degrees, the apex of the angle meeting at the Sr, creases" or folding-line 00 The tongue or stay-section d outwardly projected, is preferably and advantageously the counterpart of the portion or section between the end of the bottom section 0 and the creasing-lines x :0 and the median line :0 on the bottom is continued through the stay-sections (1 d As the box is preferably made the stay-sections 5 b are in any event no more than onehalf of the width of the end or edge walls b 0 whereby they would not overlap and stiffen the creasing-lines 00 After the box has been completed and set up and it is desired to collapse the same or knock it down the box is simply squeezed be- 5 tween its opposite sides, the longitudinal median creases m permitting theedges of the box to collapse inwardly, and the triangular sections or gusset-like parts cc 00 while collapsing inwardly or folding closely together, v

are endwise distended, together with the trapezium-shaped sections a) :0 which have as their boundaries the lines of the corners of the box, the intermediate median line 50 and the angularly-intersecting lines as 00. The tongues or stay-sections (1 which when the box is set up are as parts of the edge Walls thereof, are, because of the creasing or folding line or, continued across these stay-sections, rendered as continuations of the folding-lines a! for the box edges.

Having thus described our invention, What we claim, and desire to secure by Letters Patent, is-- A blank from which to produce a set-up and stuck rectangular box capable of being knocked down, consisting of opposite side sections a a intermediate rectangular bot tom section 0 having at the ends the tongues or stay-sections (Z d and the edge-forming sections 6 11 formed as sidewise extensions of the one side section (t and the stay-sections b Z) formed as sidewise extensions of the other side section, and having the foldinglines 1 on which to bend the blank to constitute the rectangular box, and said blank haviug the special creases as follows: the creases :6 extending longitudinally along the middle of the side sections b the crease m extending longitudinally and midway of the bottom and of the said stay-sections d 01 and the creases m :0 extending from the corners of the bottom section inwardly within the area of the unrecessed bottom section at angles of forty-five degrees to, and meeting, the creasing-line m substantially as and for the purposes described.
